Emails sent from alternate address show primary address RRS feed

  • Question

  • When our users are sending an email using a alternate address attached to their account, the recipient only sees their primary email address.

    For example:
    User has the these addresses attached to their account:

    user@domain1.com (Primary)
    user@domain2.com

    When they choose to send the email from user@domain2.com the recipient sees that the email has come from user@domain1.com


    Any help with this is appreciated as the domains are for separate companies.

    We are running Exchange 2016 on-prem Version 15.1 (Build 1415.2)

  • Exchange only uses the Primary SMTP address for sending mail, the issue and the available workarounds have been discussed numerous times here and on other resources over the internet. Here's a nice article to get you started: https://www.msoutlook.info/question/send-mail-from-additional-exchange-address-or-alias

  • Hi Richard,

    Vasil is correct. Outlook will always display the primary SMTP email address for the sender by default. There is no setting to directly change this default email address display in Exchange server.

    You can refer to Vasil's link as a workaround.
